Class PostLoadContext

Concrete CallbackContext implementation that is specific to intercepted operations that
load Entities, currently get and "query". It is important to note that when a
PostLoadContext is provided to a callback following a get operation, getElements()
returns all retrieved Entities. However, when a PostLoadContext is provided to a callback
following a query, a separate PostLoadContext will be constructed for each Entity in the result
set so getElements() will only return a List containing a single Entity. This is
due to the streaming nature of query responses.
